Troubleshooting
Problem:
I cannot access my E-mail or Internet Service.
Possible solution:
Check all connections. Make sure the cable line is securely connected to the cable
jack on the back of the modem. Verify the Ethernet or USB cable is securely
plugged into both the modem and your network interface card or USB network
interface. Make sure your Power Adaptor is properly plugged into both the
modem and a wall outlet or surge protector. If your cable modem is properly con-
nected, the Cable and PC indicator lights on the modem front panel should be a
solid color.
If the Cable and PC indicator lights (LEDs) are solid green (not blinking), your
cable modem is operating properly. Try shutting down and powering off your
computer and then turning it back on. This will cause your computer to re-estab-
lish communications with your cable company server.
1.
If you are using the cable line splitter, try bypassing the splitter by discon-
necting it and running a single coaxial cable between the cable modem and
your cable wall jack. Try reconnecting after making this change. If recon-
necting is successful, you may have a bad splitter.
2.
Your network interface card may be malfunctioning. Refer to the Manufac-
turer's documentation for troubleshooting information.
3.
Call your cable company to verify their service is two-way. This modem is
designed for use with two-way cable plants. Verify your account is activated.
